Fix code review issues in TeamScoreBreakdown sortable table

- Move SortIndicator out of render (avoids remount on every render)
- Extract sortPicks helper outside component
- Restore default sort: sport name then pick number (was lost in prior commit)
- Replace unicode arrow chars with Lucide ArrowUp/ArrowDown/ArrowUpDown icons
- Add aria-sort attributes to sortable column headers for accessibility
- Change w-[90px] to min-w-[90px] on Pick # column to avoid clipping
- Flatten nested div inside Points sort button
